zhiweijian b9a1756202 fix(ble/bluedroid): Remove BLE functions discard declaration 
fix(nt/bluedroid): Split the device name set functions

feat(bt/bluedroid): added APIs to get/set device name on BT GAP side

change(bt/common): Marked some APIs in device module as deprecated

1. esp_bt_dev_set_device_name
2. esp_bt_dev_get_device_name

change(bt/bluedroid): use BT GAP APIs to set/get device name in bluetooth classic examples

change(bt/bluedroid): use BT/BLE GAP APIs to set/get device name in coexist examples

Supported Targets ESP32 ESP32-C2 ESP32-C3 ESP32-C6 ESP32-H2 ESP32-S3

ESP-IDF BLE throughput GATT SERVER Test

This is the demo used to test the BLE throughput, this demo should used with throughput client demo together. The throughput of BLE can up to 720-767 Kbps between to ESP32 board.

How to Use Example

Before project configuration and build, be sure to set the correct chip target using:

idf.py set-target <chip_name>

To configure the project, you can follow these steps:

  1. In order to maximize throughput, we need to set the uart print baud rate at 921600 or more: Go to: idf.py menuconfig --> Component config --> ESP32-specific --> UART console baud rate and set to 921600 or 1500000 and don't print too much log.
  2. We can only test notify or write throughput at the same time, this demo default to test the notify throughput, if want to test the write throughput, please set: idf.py menuconfig --> Component config --> Example 'GATT CLIENT THROUGHPUT' Config ---> then select the test the gattc write throughput option.
  3. This demo only test unidirectional throughput, if you want to test the bidirectional throughput please change the demo by yourself.
  4. Should change the CPU frequency to 160 MHz or 240 MHz in the idf.py menuconfig and Component config ---> ESP32-specific ---> CPU frequency (240 MHz or 160 MHz).
  5. Should change the bluetooth controller and Bluedroid run in different Core in the idf.py menuconfig on Component config ---> Bluetooth ---> The cpu core which bluetooth controller run (Core 0 (PRO CPU)) and Bluedroid Enable ---> The cpu core which Bluedroid run (Core 1 (APP CPU)).
  6. In order to maximize throughput, please test in a clean environment without many BLE devices working and both test devices are ESP32.

Hardware Required

  • A development board with supported SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
  • A USB cable for Power supply and programming

See Development Boards for more information about it.

Build and Flash

Run idf.py -p PORT flash monitor to build, flash and monitor the project.

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
